Signup & verification

Write a signup verification email people understand

Give new users one clear action and explain what happens when the link no longer works.

By Claire from Venmail

A verification email should answer three questions immediately: which product is this, what should I do, and what if I did not request it? Keep marketing out of this message. The reader is trying to finish a task, often with the signup page still open.

The 30-minute period is an example, not a Venmail setting. Your application must enforce the period you state. If the product actually expires links in ten minutes, the email and the error page should say ten minutes too.

Connect the copy to the product

  1. 1

    Use a recognizable sender

    Send from an address authorized for your Venmail account and identify the product in the From name. Provide a monitored support route. Do not ask the user to reply with their password or confirmation token.

  2. 2

    Generate the link in the application

    Use your authentication framework to create a purpose-bound confirmation. Build the destination from an approved application origin, not a host value supplied by the visitor. Keep tokens out of analytics logs.

  3. 3

    Make the button and fallback agree

    Both should lead to the same approved confirmation flow. The landing page should say whether confirmation succeeded, expired or was already completed. A generic error leaves users guessing whether they should sign up again.

  4. 4

    Test difficult cases

    Send the template to a mailbox you control. Try a slow arrival, an expired link and a second click. Check the plain-text message as well as the designed version. Confirm that email scanners do not consume a token before a person confirms.

React Email is a free option for developers who want a reusable template. A plain message also works. Venmail can carry the email, while the authentication framework controls whether the account becomes verified.

You can build and test this workflow with free software. For live sending, check API or SMTP access and the sending allowance in your Venmail account; the public Free workspace offer is not a promise of a free production API quota. Venmail, Venmail
